Archie:
I want to thank you for the great job you have done developing AdavancedHMI controls and dlls.
I have been using the old version (before r or may be t) of your AdvancedHMIDrivers.dll and MfgControl.AdvancedHMI.Drivers.dll in my VB.net 2010 to read 2 Tags off AB CompactLogix PLCs. Here are the statements I use in my code to Read 2 Tags off 2 PLCs:
Imports AdvancedHMIDrivers
Public Class MainForm
Public AbPLc(2) As EthernetIPforCLXCom
Private Sub MainForm_Load(sender As System.Object, e As System.EventArgs) Handles MyBase.Load
AbPLc(1) = New EthernetIPforCLXCom
AbPLc(1).IPAddress = "192.168.1.207"
AbPLc(1).Timeout = 1000
AbPLc(2) = New EthernetIPforCLXCom
AbPLc(2).IPAddress = "192.168.1.204"
AbPLc(2).Timeout = 1000
End Sub
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim DataStr As String
Try
DataStr = AbPLc(1).Read(Tag1.Text)
Lab1.Text = DataStr
Application.DoEvents()
DataStr = AbPLc(2).Read(Tag2.Text)
Lab2.Text = DataStr
Catch ex As Exception
MsgBox(ex.Message)
End Try
End Sub
End Class
As soon as I replace the above 2 dlls with their new version v, or w, I get the error message”
“Read Failed. Path Segment Error (Invalid Tag Name), Status Error=4”
It is my understanding that as of version 3.99r only Ethernet card routing is available. My problem is that I do not know what Routing Path I should use to make my application work with the latest version of dlls.
I can ping the 2 IP address and I have access through Rslogix5000 or Linx but not with the latest version of your AdvancedHMI.libraries.
Any help that you can provide me to make my application work with version w is greatly appreciated.
Thanks
Khosrow
